I don't know the exact requirements, but I would deffinitely call Flight Safety and find out, they will ask for passports, ID's Visas, etc, as soon as you arrive and if you don't have them in order you won't be getting in the Sim, and probably won't be allowed to attend class until you get it sorted out.
The last time I was at FS we had an FAA inspector attending class and he had forgotten his US passport, there were a few awkward moments for the Instructor until the inspector left class and made arrangements to get the passport.
